Chris, friends, etc:

I've got a very similar set-up on Rags: 79 engine, header, free-flow
exhaust. However, I've got a Lucas 25D dizzy on the engine ... one from
an older (pre-75) MGB.  I've got a Weber DGV 32/36 carb on the car.

Right now, I've got the vaccuum advance on the distributor closed off,
idle advance set at 15deg BTDC @ 1500 rpm.  I'm not interested in
replacing the cam.  Two questions:

1) Has anyone any experience with changing the idle advance, and what
are some good settings? Rags is pretty happy with 15 deg, but I lack
power on takeoff (witness being smoked by a minivan last week).

2) If I were to attach the vaccuum advance to something, does anyone
know where on the DGV it should go? And what might be the practical
advantages of this?  Rags has pretty good power from 2500 rpm to around
4800 or so, when it starts to level off.  I usually shift around 3800
or so in normal traffic.

Thanks!
